Question

Rate of a reaction can be expressed by Arrhenius equation as : $k = Ae^{-E/RT}$ In this equation, E represents :

• A. the energy above which all the colliding molecules will react
• B. the energy below which colliding molecules will not react
• C. the total energy of the reacting molecules at a temperature, T
• D. the fraction of molecules with energy greater than the activation energy of the reaction

Answer 1

Answer: (B)

the energy below which colliding molecules will not react

Answer 2

$k = Ae^{-E/RT}$ E is activation energy, it is that energy, which molecule must have to give the product.
